TEMPLET.

Application filed April 22, 1909. Serial No. 491,531.

Specification of Letters Patent.

Patented Aug. 10, 1909.

To all whom it may concern:

Be it known that I,.WALTER C. Wnsr, a citizen of the United States,residing at Pleasant Green, in the county of Cooper and State ofMissouri, have invented a new and useful Templet, of which the followingis a specification.

The objects of the invention are, generally, the provision in amerchantable form, of a device of the class above mentioned, which shallbe inexpensive to manufacture, facile in operation, and devoid ofcomplicated parts; specifically, the provision of a templet the fiducialmembers of which are arranged to be brought into parallelism and to bedisposed at an angle to each other, means being provided for maintainingone of said members in terminal advancement beyond the other, formaintaining the advanced end of the one member at a fixed distance fromthe corresponding end of the other member, and for adjusting thedistance between the ends of the said members which are not thusmaintained at a fixed distance apart; other and further objects beingmade manifest hereinafter as the description of the inventionprogresses. p

The invention consists in the novel construction and arrangement ofparts hereinafter described, delineated in the accompanying drawings,and particularly pointed out in that portion of this instrumentwhereinpatentable novelty is claimed for certain distinctive and peculiarfeatures of the device, it being understood that within the scope ofwhat hereinafter thus is claimed, divers changes in the form,proportions, size, and minor details of the structure may be made,without departing from the spirit or sacrificingany of the advantages ofthe invention.

In the accompanying drawings Figure 1 shows in perspective, my inventionin open position; Fig. 2 is a bottom plan showing the same closedtogether; and Fig. 3 is a perspective of a modified form of side member.

The improved templet forming the subject matter of this application forLetters Patent may be put to a wide variety of'uses. adapted to beemployed in any case where it is desired to take ofi a rectilinearfigure of irregular contour and to lay out the same on the materialwhich is to be worked. To mention a concrete casein which the device maybe employed to advantage, it may be said that it will be found useful inascertaining the shapes of risers and treads when stair- It is.

applied to the mechanical solution of many problems which are presentedin practical form to the carpenter and joiner.

The invention comprises primarily, a rib 1 provided along itslongitudinal center with a slot 2. Upon either side of the rib 1 aredisposed side members 3, braces 4 being provided, the remote 'ends ofwhich are pivotally assembled with one end of the side members 3, theadjacent ends of the braces being pivotally assembled with the rib 1.

The braces 4 constitute a means for maintaining the side members at afixed distance apart at one end and means are provided for adjusting thedistance between the other ends of the side members, the last-namedadjusting means in the present instance consisting of links 5 providedalong their longitudinal centers with slots 6. The remote ends of theselinks 5 are pivotally assembled with those ends of the side members 1which are remote from the pivotal attachment between said side membersand the braces 4. The adjacent ends of the links 5 are arranged tooverlap, and through the slots 6 in their overlapping portions is passeda clamping screw 7 the terminal of said member 7 being assembled withone extremity of the rib 1, the said member 7 constituting a meanswhereby the links 5 may be clamped in a fixed position with respect toeach other and with respect to the rib 1 upon which the adjacent ends ofsaid links 5 are adjustably mounted.

Ties 8 are provided, the remote ends of which are pivotally assembledwith the braces 4., intermediate the ends thereof, the adjacent ends ofsaid ties being arranged to overlap and being apertured to receive a setscrew 9 adapted to reciprocate in the slot 2 of the rib, the said ties 8and the set screw constituting a means whereby the braces 4 may beclamped in a fixed position with respect to the rib 1.

The pivotal connection between the braces 4 and the side members 3 maybe effected by any conventional means adapted to the end sought. In thepresent instance, I have cleft the ends of the braces and side membersto receive pivot plates 10 with which the ends of the braces and sidemembers are pivotally connected. In fashioning the pivotal connectionbetween the adjacent ends of the braces 4 and the rib 1, plates 11 maybe disposed upon opposite faces of the rib 1, the extremities of thebraces 4 being pivotally mounted between said plates. The fidueial edgesof the side members 3 may be beveled as denoted by the numeral 12, andupon these side members may be inscribed graduations 14 which may be ofany form adapted for use in the art in which the invention is to beemployed. The ends of the side members 3 adjacent the pivotal connectionbetween said side members and the braces 45, are provided with points15, in order that the said side members may set fairly against anobstacle when employed as hereinafter described, and in order that thepositions determined by the extremities of said side members may bedefined accurately.

In practical operation,.the device may be placed in position, betweentwo walls, supposing a concrete case, and, the set screw 9 having beenloosened, the pointed ends 15 of the side members may be spaced apart tothe required distance. The set screw 9 may then be tightened, but sincethe union between the side members 3 and the braces 4 is a pivotal one,the ends of said side members with which the links 5 are assembled, maybe moved laterally, to cause the side members 3 to assume the desiredangle with respect to each other. When the side mem bers are thusproperly positioned, the set screw 7 may be tightened, and the device,in

rigid condition, be transferred to the material, the shape assumed bythe device being laid down thereon. Owing to the manner in which theseveral component parts of the device are assembled with each other, oneof said points 15 may be advanced beyond the other, whereupon saidpoints 15 may be clam ed, the other extremities of the side mem ers 3being thereupon adjusted by means of the links 5, to any requireddistance apart. It is to be noted that the rib 1 is not a fixed member,the end thereof which is remote from the links 5 being movable towardthe braces 4, this movement in the extremity of the rib 1, makingpossible the advancement of one of the points 15 beyond the other.

The order in which the foregoing adjustments have been described, neednot be rigidly adhered to, it being obvious that by loosening the setscrews 7 and 9, the device may be shifted at will to define a widevariety of rectilinear figures. The angle between the side members 3,and the relative positions of the points 15, having-been determined,width maybe read off upon the graduations 14 along the fiducial edges ofthe side members 3.

If desired, reinforcing members 16 may be superposed upon the ties S,and the rib 1 may be channeled as denoted by the numeral 17 adjacent theslot 2 to receive as it slides, the head of the member 9. The edges ofthe braces 4 may be cut away as denoted by the numeral 18 to receive therib 1, when, as shown in Fig. 2, the device is closed into compact form.

In the form shown in Fig. 3, the modification consists in beveling theedges of the members 3 as denoted by the numeral 12 in order tofacilitate the laying oil of dimensions.

Having thus described my invention, what I claim as new and desire toprotect by Letters Patent is:

1. A device of the class described. comprising a rib; side membersdisposed upon either side of the rib; braces pivoted at their remoteends to one end of the side members, and at their adjacent ends, to therib; links pivoted at their remote ends to the other ends of the sidemembers, the adjacent ends of the links being adj ustably assembled withthe rib; and ties, having their remote ends pivotally mounted upon thebraces, their adjacent ends being adjustably assembled with the rib.

2. A device of the class described comprising a rib; side membersdisposed upon either side of the rib braces pivoted at their remote endsto one end of the side members, and at their adjacent ends, to the rib;ties having their remote ends pivotally mounted uponthe braces, theiradjacent ends being adjustably assembled with the rib; and meanspivotally assembled with the other ends of the side members andadjustably assembled with the rib, for spacing said ends of the sidemembers apart.

In testimony that I claim the foregoing as my own, I have hereto ailixedmy signature in the presence of two witnesses.
